animation
The following code specifies the default value of the object:
{ show: { type: 'fade', from: 0, to: 1 }, hide: { type: 'fade', from: 1, to: 0 } }
Set this object to null
or undefined
to disable animations.
closeOnOutsideClick
Use the hideOnOutsideClick property instead.
Specifies whether to close the UI component if a user clicks outside the popover window or outside the target element.
Event (jQuery or EventObject)
The event that caused UI component closing. It is a EventObject or a jQuery.Event when you use jQuery.
true if the UI component should be closed; otherwise false.
container
Specifies the container in which to render the UI component.
This property accepts one of the following values:
A CSS selector, or a jQuery selector if you use jQuery
jQuery
index.js$(function(){ $("#popoverContainer").dxPopover({ // ... container: '#containerElement' }); });
Angular
app.component.html<dx-popover ... container="#containerElement" > </dx-popover>
Vue
App.vue<template> <DxPopover ... container="#containerElement" > </DxPopover> </template> <script> import { DxPopover } from 'devextreme-vue/popover'; export default { components: { DxPopover } }; </script>
React
App.jsimport Popover from 'devextreme-react/popover'; // ... function App() { return ( <Popover ... container="#containerElement" > </Popover> ); }
A jQuery wrapper
jQuery
index.js$(function(){ $("#popoverContainer").dxPopover({ // ... container: $('#containerElement') }); });
A DOM element
jQuery
index.js$(function(){ $("#popoverContainer").dxPopover({ // ... container: document.getElementById('#containerElement') }); });
Angular
app.component.htmlapp.component.ts<dx-popover ... [container]="containerElement" > </dx-popover>
// ... export class AppComponent { containerElement: Element; constructor() { this.containerElement = document.getElementById('#containerElement') as Element; } }
Vue
App.vue<template> <DxPopover ... :container="containerElement" > </DxPopover> </template> <script> import { DxPopover } from 'devextreme-vue/popover'; export default { components: { DxPopover }, data() { return { containerElement: null } }, mounted() { this.containerElement = document.getElementById('containerElement'); } }; </script>

The UI component defines the default container on its initialization. This default container can be one of the following (if the element is absent, the component selects the next one):
.dx-viewport
body
copyRootClassesToWrapper
Copies your custom CSS classes from the root element to the wrapper element.
This property allows you to use CSS for wrapper element configuration. You can customize the shade, resize, and drag zones.
The following markup illustrates relations between wrapper and root elements when you set copyRootClassesToWrapper to true:
<body> <!-- The following element is the root element on which the component is initialized. --> <!-- Specify classes to be copied to the wrapper element here. --> <div id="popover" class="custom-class" ... ></div> <!-- The following element is the wrapper element. --> <!-- Custom classes are automatically copied from the root element. --> <div class="dx-overlay-wrapper dx-popover-wrapper custom-class" ... > <!-- The following element contains component content. --> <div class="dx-overlay-content" ... > <!-- ... --> </div> </div> </body>
deferRendering
